The majority of Labour MPs seem to have realised that they need to get the party properly united behind the leader now. Many have been gracious in acknowledging they misjudged and underestimated Corbyn (although how much of that is typical Westminster weathervanism and how much is genuine remains to be seen).

Leslie is on his own to a large degree, but then I believe his wife ran an anti-Corbyn group at one point, so he's truly lost in Blairism.
